Hello dear, thanks for your question on HCM.
I can understand your situation and problem.
You have been treated for GERD and still not improving.
In my opinion you should
consult pulmonologist and get done PFT ( pulmonary function test ) to rule out
bronchitis first. As bronchitis can cause similar symptoms.
If this is also normal then you are having mostly GERD (
gastroesophageal reflux disease ). And
endoscopy is needed to diagnose this.
So get done endoscopy.
For better control of GERD you need to follow these lifestyle modifications along with drugs.
1. Avoid hot and spicy food.
2. Avoid stress and tension.
3. Avoid large meals, instead take frequent small meals.
4. Go for walk after meals.
5. Keep 2 - 3 pillows under head in bed to prevent reflux.
6. Avoid alcohol and
smoking, if you have these habits.
7. Loose weight if you are obese.
Don't worry, you will be alright.
